SAW CLAMP.

Application fi1(.l October This invention relates to holding devices,and more particularly to a saw vise.

One of the main objects of the invention is to provide a saw vise ofsimple construction which, when not in use, can be readily disassembledand folded so as to occupy a minimum of space, this Vise beingparticularly well adapted for use by carpenters and other tradesmen. Afurther object is to provide a saw vise which can be readily applied toa vertically disposed support. Further objects will appear from thedetailed description.

In the drawings:

F211. is a detail ou one pair of ari'ns of one of the supportingmembers.

T he device includes two supporting structures and means for forcing thesame toward each other for tightly gripping between the jaws carried bythe structures the blade of the saw. Each supporting structure includestwo supporting arms 1 which are hingedly secured together at their lowerends as at 2. Each arm is provided, at its upper end, with an angularlydisposed stud 5 which is adapted to lit snugly into a corrcsj'mnilingsocket 6 formed in a clamping jaw 7, these sockets I being remote fromeach other and the arms 1 diverging upwardly toward the jaw. Two bars 8and 9 extend across the respective supporting structures intermediatethe ends thereof and one of these bars carries rods 10 each provided atone end with an eye 11 which is pivotally secured by a pin 12 in a slot18 cut in the end of bar 8 for this purpose. Rods 10 extend throughopenings provided in bar 9 for this purpose and are slid-' able throughthe bar. A headed pressure screw 14 is secured through bar 8 and isslidable through an opening 15 provided through bar 9, this screw beingdisposed centrally of the bars. A wing nut 16 is threaded onto the screw14 and bears against the outer face of bar 9. The rods 10 are so 2,1925. Serial No. 60,115.

spaced as to be positioned in'contact with the outer lateral faces ofarms 1 when the bars 8 and 9 are so positioned that rods 10 contact withshoulders 17 formed on arms 1 to limit upper movement of the rods.

In using the vise the supporting structures are placed with their lowerportions at opposite sides or a suitable support, such as a board 18which may be secured across a window or door opening, or in any othersuitable position, in any suitable manner. The saw blade B is theninserted between jaws T and by threading nut 16 onto screw 14 the jawsare forced toward each other so as to clamp the saw blade andtightlysecure it in position. If desired, though not necessarily, asuitable pressure screw '4 of known construction may be threaded throughhollow pivot 3 of one of the hinges 2 to more tightly clamp these pivotsagainst board 18.- The pressure exerted by this screw will alsosupplement, to a. certain extent, the pressure exerted by screw 14 andnut 16 so as to more tightly grip the saw blade between the jaws 7. Thisprovides a vise of very simple and inexpensive construction which can bereadily applied in such a location as to insure the proper light forfiling or sharpening the saw blade. When this vise is not in use itcanbe readily disassembled by removing the jaws 7 permitting the arms 1 tomove inwardly toward eachother about their pivots, after which the bars8 and 9 and associated parts can be readily slid downwardly off of thearms, the vise in its disassembled condition being readily packed so asto occupy but very little space. This renders it particularly welladapted for use by carpenters and other tradesmen as it can be readilytransported in the usual tool kit.

As will be understood, and as suggested herein, changes in constructionand arrangements of parts of the invention may be resorted to withoutdeparting from the field and scope of the same and I intend to includeall such variations, as fall within the scope of the appended claims, inthis application in which a preferred form only of my invention isdisclosed.

I hat I claim is:

1. A device of the class described including clamping jaws, supportingmembers pivotally connected together in pairs and having connection withthe clamping jaws. means providing said connection between the lit? .and a structure having portions engaging the opposite correspondlnglateral sides of V clamping jaws and the supporting members,

and means for urging the clamping jaws into clamping relation withrespect to an article disposed between the clamping jaws,

said means including a clamping member,

.he supporting members and having other portions engaging oppositecorresponding 7 movable means; Iittin about the sun ortin i .L b

jstructures intermediate the ends thereof for forcingsaid structurestoward each other;

In a-saw clamp, a pair of supporting structures each including a pair orarms hingedly connected at their lOiWQlf ends, jaws removably mountedonthe upper ends of the arms: of the respective structures, the 1 arms;diverging toward the jaws, and removable means fitting about thesupporting structures: intermediate the ends thereof for forcmg saidstructures toward each other, said means acting to guide the supportingstructures and to hold themein proper relation toeachother.
